Continuity mistake: Doc Riedenschneider calls on Cobby in a dark hallway with brick walls and a door in the end with a half-open transom. Through this door, in the adjacent room, there are several gangsters seated a table. They go down the hallway and enter this room. In the next scene they have entered and the seated gangsters are suddenly no longer there. Nor is there a transom over the door. The hallway viewed from this room has white walls now instead of brick.
Factual error: Between Earth and the Moon the crew of the spacecraft have an EVA in which they walk on the ship's metal hull with magnetic boots. At one point an astronaut inadvertently slips both boots off the hull and drifts off into space, helpless. There is a long shot of him drifting away in which his body spontaneously spins around 180 degrees and then stops rotating, which is all a violation of conserved angular momentum.
Continuity mistake: When Elwood P. Dowd and Harvey are entering the bar, Elwood is holding a hat by the top, with his left hand. When they are in the bar, Elwood is now carrying the hat by rim.
Factual error: When the two escapees from the POW camp are in the anchor room of the ship they are on, they leave the harbour and the pilot boat leaves them, but then the chain for the anchor goes out, but they are moving away from the port, why on earth would they be dropping the anchor? If anything they would make sure that all the chain is in the anchor room and the anchor would be on deck.kh1616
